CTM Continuous Toxicity Monitoring Early Warning System TM Online Real-Time Detection of Toxic Agents in Water and Wastewater DIMENSIONS: 60 CM WIDE, 94 CM HIGH, 45 CM DEEP Monitoring of water toxicity using biosensors has become a widely accepted technique. Bacterial biosensors offer simple and reproducible tests that can be automated, with reagents that can be stored. Biosensor tests using bioluminescent bacteria have been in use for 30 years and their capability in detecting toxic substances is well understood but existing tests are offline or intermittent and require high levels of skilled operator intervention. The new CTM™ Continuous Toxicity Monitor makes fully automatic, continuous, on-line testing a reality. SPECIFICATIONS Sample Requirement 200 ml/h at ambient pressure. Fast sampling loop available if required Sample Temperature 1-30oC (automatic temperature correction) Connections 2.2mm tube with luer couplings Electrical 230V 50Hz AC 250W Control system Industrial PLC Display Colour 120x90mm touch sensitive Communications Ethernet, USB port for data download Communications options 4-20 mA loop, relay alarm output(s) Consumables Replaced every 4 weeks Auto Calibration Interval (control/blank) User settable between 3 and 24 hours Standard 5 mg/l zinc sulphate Maintenance 2 hours per month Waste volume 120 l/month – non-toxic, suitable for soak-away Autosampler Takes samples on positive alarm (optional) Weight 60kg (approx) Dimensions (main enclosure) 985x590x460mm (HxWxD) Housing Ventilated housing IP44 Bioreagent Water Water to be tested Pump Name Drain Light detector ...................................................................................................

When they are exposed to toxic substances, the amount of light emitted reduces. The greater the toxicity of the sample, the lower the light emitted. This has been shown over many years to be a reproducible effect. Measuring changes in light between healthy bacteria and bacteria exposed to toxic substances will therefore indicate presence in a water sample. What it detects The CTM™ Continuous Toxicity Monitor automatically and simultaneously detects a broad range of toxicants including metals, pesticides, fungicides, herbicides, chlorinated solvents, industrial chemicals, algal toxins. The presence of harmful contaminants in waters and wastewaters is detected without having to monitor for a wide range of specific chemicals. Applications include •Deliberate and accidental contamination events •Water intake protection •Potable and make-up water quality at point of use •Monitoring of rivers, lakes, reservoirs, seawater •Industrial effluent monitoring •Groundwater monitoring / natural attenuation •Wastewater recycling •WWTP influent monitoring Features •Real time and truly continuous monitoring •Continuous unsupervised operation for 1 month •No manual intervention except for monthly maintenance (2 hours per month) •Reagents can be stored at room temperature •Automatic diagnosis of system faults •Remote control, data analysis and troubleshooting •Detects thousands of chemical compounds at lower levels of contamination than most other biosensor systems •Option to test multiple water sources •Operating costs not dependent upon no. of tests
